Patented Apr. 5, 1932 UNITED STATES HUBER! E. HILL, OF MEMPHIS,TENNESSEE TOOL Application filed April 27,

This invention relates to a tool primarily adapted to remove and replacean ignition cable now in use 011 certain automobiles, in making repairs.

The objects of the invention are:

To provide means for securely engaging the two parts which are to beseparated, each to a clamp, and for forcibly separatnig these clamps todisengage the parts, and reversely for forcibly approaching the twoclamps to engage parts carried thereby together; and

To simplify the design and construction of such a tool.

The means by which the foregoing and other objects are accomplished andthe man-- nor of their accomplishment will readily be understood fromthe following specification on reference to the accompanying drawings,in which:

Fig. l is a longitudinal sectional elevation of the tool showing itapplied to a special type of ignition cable lock, and ready to separatethe parts thereof;

Fig. 2 is a corresponding inverted plan view; and

Fig. 3 is a sectional elevation taken on the line III-III of Fig. 2.

Referring now to the drawings in which the parts are referred to bynumerals, 10 is an ignition cable which terminates in a sleeve 11, theend of which is disposed in a recessed cylindrical block 12. 13 is aportion of the distributor box to which the cable is secured. From thisbox a rigidly held pin 1 1 having a bayonet shaped head 15 projectscentrally through the block 12. Disposed within the sleeve 11 is a thinmetal washer 16, having a star shaped central hole which is held against removal by an annular externally threaded retaining ring 17, thehole in this-ring being larger than the bayonet head 15. 18 is aninsulating ring and 19, a spring holding the washer against these rings.

The tool comprises a pair of substantially U-shaped clamps 20, 21arcuately chambered out to fit over the sleeve 11, and block 12.respectively. The engaging surface of clamp 20 is provided with V-shapedthreads 22, to engage and bite into the cylindrical surface of thesleeve 11 and thereby secure a grip for 1931. Serial No. 533,035.

removing the sleeve and with a shoulder 23 to engage the end of thesleeve in replacing it.

The clamp 21 is provided with flanges 24, 25 to engage the ends of theblock 12. Each of the clamps is provided with a set screw 26, 27respectively, through which engagement of the clamps with the sleeve andblock respectively, is completed.

Secured in and projecting from the clamp 21 are parallel guides 28,preferably smooth round rods, which pass through and have a sliding litin complementary holes in the clamp 20.

29 is a screw, disposed parallel to these guides. which threadedlyengages the clamp 85 20, and is rotatably mounted in the clamp 21.Longitudinal movement of the screw relative to clamp 21 is prevented bythe collar 30 and nut 31.

In using the tool the clamps 20 and 21 are brought close together. Clamp21 is engaged over block 12, and clamp 20 over sleeve 11, and each isengaged to its respective part by the set screws 27, 26, the latterscrew especially being set up tight enough to cause the threads 22 tobite into and engage -the sleeve.

Screw 29 is then turned by a suitable wrench to separate the clamps andforcibly withdraw the sleeve 11 from the block 12, in so doingdistorting and destroying the washer 16. After such disconnection theclamps are disengaged from the sleeve and block.

After removal the threaded ring 17 becomes accessible and may be removedto permit repair of the cable end, or a new cable and sleeve may be putin. In either event, the cable and attached sleeve 11 may be replaced byre-engagement of the clamps with the sleeve and block and turning thescrew 29 to draw the parts together.

Having described my invention, what I claim is:

1. A tool, comprising a pair of U shaped clamps having arcuate engagingsurfaces,

U shaped partengaging-flanges at opposite ends of one of said clamps,corrugations in the engaging surface of the opposed clamp and set screwspassing each through a leg of a clamp for securing in said clamps partsto be separated or engaged, and a screw rotatably secured againstlongitudinal displacement in one of said clamps and engagingcomplementary threads in the other of said clamps whereby said clampsmay be forcibly separated or approached.

2. A tool, comprising a pair of clamps having arcuate engaging surfaces,part-engaging-flanges at opposite ends of one of said clamps,corrugations in the engaging surface of the opposed clamp and means forsecuring in said clamps parts to be separated or engaged; one of saidclamps having parallel guides extending from one end thereof and theother of said clamps having complementary holes through which saidguides are slidably disposed, anda screw disposed par allel to saidguides, rotatably secured against longitudinal displacement in one ofsaid clamps and engaging complementary threads in the other of saidclamps whereby said clamps may be forcibly separated or approached.

3. A tool, comprising a pair of U shaped clamps having arcuate engagingsurfaces, U shaped part-engaging-flanges at opposite ends of one of saidclamps, corrugations in the engaging surface of the opposed clamp andset screws passing each through a leg of a clamp forsecuring in saidclamps, parts to be separated or engaged; one of said clamps havingparallel guides extending from one end thereof and the other of saidclamps having complementary holes through which said guides are slidablydisposed, and a screw disposed parallel to said guides, rotatablysecured against longitudinal displacement in one of said clamps andengaging complementary threads in the other of said clamps whereby saidclamps may be forcibly separated or approached.

4. A tool, comprising a pair of U shaped clamps having arcuate engagingsurfaces, U shaped part-engaging-flanges at opposite ends of one of saidclamps, corrugations in the engaging surface of the opposed clamp andset screws each passing through a leg of a clamp for securing in saidclamps parts to be separated or engaged, one of said clamps havingparallel guides extending from one end thereof and the other of saidclamps having complementary holes through which said guides are slidablydisposed, and means for forcibly advancing or retracting one of saidclamps toward or away from the other thereof and along said guides.

In testimony whereof I hereunto affix my signature.

HUBERT E; HILL.
